Upward, through the ether blue, 

 Seeing stars which ever keep 



Hidden close from human view. 



It is common in Europe and among the Swiss, when worn on 

 the person in company with rue, agrimony, maiden-hair and broom 

 straw, is thought to confer fine vision and to point out the pres- 

 ence of witches. The foliage was used in England until the time 

 of Henry YTTT to clarify and give a flavor to ale, but at that period 

 was replaced by hops. The odor of" the leaves is exhaled freely and 

 is strongly penetrating and peculiar, yet pleasing to him who, 

 through long experience, has learned to expect it on his daily walks.

 and yards, resodding or spading and reseeding must be done, while 

 in fields fences should be removed and thorough cultivation used.

sandy soils. June-Sept. Like the 

 catnip and ground ivy it was 

 brought from Europe, but is more 

 unsightly and useless than either of 

 them. It was once much used in 

 nervous and hysterical complaints 

 and an infusion of its leaves taken 

 at bedtime is said to produce sleep. 

 In March one often sees standing 

 stiffly erect, like brown monuments 

 of the past, the 4-angled stems of 

 last year's motherwort. On them 

 the dry fruit is in dense sessile 

 clusters an inch and a half apart.
